As shown in FIGS. 4 and 5, thelongitudinal cross sectional view along A-A of FIG. 3 the decorationacoustic board and transversal cross-sectional view along B-B of FIG. 3are illustrated. The decoration acoustic board 10 b having a substrate12 first made from solid wood or chip wood, and then processed throughfireproof treatment to mix with fire resistant resin; finally, the mixedresin substrate is compressed to form a decoration board. A plurality ofguide slots 121 are formed equidistantly on the front of the substrate12, and the bottom 122 of the guide slots 121 are in the shape of wavedform. A plurality of slots 124 spaced equidistantly from one another aredistributed on the underside of the substrate 12. A plurality of holes123 shaped in the same or different sizes are formed through thesubstrate 12 in communication with both of the guide slots 121 and slots124.

The width of the guide slots 121 is larger than the slots 124, forexample, such as the width of the guide slots is 1.0 cm, and the slotsare 0.2 cm. The dimensions and numbers of the guide slots 121 located onthe front of the substrate 12, that would affect the function ofabsorbing sound waves and the decoration of designed patterns thereof.To obtain the balance, the above mentioned dimensions, such as the guidehole 1.0 cm in width, the slot 0.2 cm in width, is the preferred size;while the depth of the guide slots 121 can be designed as deeper orshallower as required. Other than the designed patterns added to thesubstrate surface, after the sound waves entering into the guide slots121, can go through the slots 125 by holes 123. Thereby, the sound wavesare reflected and compressed within the holes and the slots, thefrequency and volume of the sound waves are reduced and absorbed. Inother words, the vibration amplitudes of sound waves are buffered withinthe holes 123 and slots 125. The waved bottom 122 also shows a gracefulstreamline appearance that results in a preferred acoustic, decorative,pervious to light, and ventilating effect.
